(us media revealed that the largest fraud in US history involved $280 billion). According to a report by the Associated Press on 12 June local time, of the US $4.2 trillion in aid distributed by the US government during the COVID-19 epidemic, more than 280 billion US dollars were "stolen" by fraudsters, which is also the largest fraud in US history. According to reports, at the beginning of the epidemic, there were huge loopholes in the approval process of the US government's aid for the COVID-19 epidemic, such as the implementation of the economic loss disaster loan plan and the salary protection plan. Borrowers are allowed to "self-prove" the authenticity of the loan, and the US small Business Administration does not have the right to view the tax returns of applicants. Some experts believe that the lack of supervision by the government and very few restrictions on applicants make it easy for fraudsters to succeed.
